Abstract
The invention comprises a method for generating a biocide, comprising the steps of generating a solution of polymers comprising charged amines on nitrogen containing repeating backbone monomers, the solution comprising chloride anions as counterions to greater than fifty percent of the charged amines and a pH less than four; and subsequently: (1) increasing a pH of the solution by at least one pH unit and (2) decreasing the chloride anion concentration of the solution by at least five percent to yield a reduced chloride anion solution, the reduced chloride anion solution yielding the biocide, the biocide inactivating, with physical contact for greater than two minutes, both: greater than fifty percent of a bacteria and fifty percent of a virus. Methods of increasing the pH and decreasing the chloride concentration optionally include increasing the pH, forming a solid salt, rinsing and lowering the pH and/or using an anion exchange material.
